I have read a few posts in this section, but it is totally impossible for someone like me (new to smartphones, flashing and the rest) to understand anything. Would you please explain some of the terminologies used here? Some of them are: kernel, 3g, port, system.ext2, BT... and thousands more.
Thank you very much!
you don't really "need" to understand any of that.
all you need to do is to learn how to download files, learn how to extract the downloaded file, learn how to copy them to an sd card, and learn how to run a program inside windows mobile.
if you can do all that, you should be set!!!
just follow steps 1-6 (ignore step 1b - the part about system.ext2) - http://forum.xda-developers.com/showthread.php?t=951962
Well noted AkumaX. Thank you very much!
XDAndroid is a project to port Android onto older HTC phones.
There are two main parts of XDAndroid, which combine to form a complete port:
Kernel/drivers: You can find packages to run Android on old HTC phones from a variety of sources, but whatever package you use, all rely upon the kernels/drivers created by the XDAndroid team to enable the basic hardware.
Android system: The Android system forms all of the parts of the phone's interface that you can directly interact with. Once the kernel/drivers have setup the hardware, you can add on an Android system port of your choice to form a complete build. Many system ports are available, both in terms of different versions (2.1 Eclair, 2.2 Froyo, 2.3 Gingerbread, etc.) and different starting points in the case of ports written by those outside of XDAndroid.
XDAndroid releases an "official" system port you can use, which is directly ported over by the XDAndroid team from the Android Open Source Project, and is very close to stock. Many of the alternative builds you come across are modifications of the XDAndroid system, containing customizations that deviate farther from stock Android, while others have different starting points altogether, and are ports of the ROMs found on official shipping devices that have already been customized (but still use the same basic kernel/drivers found here).
Android is a framework that runs on top of Linux. In order to get Android running on our devices, first we must get Linux running on the hardware with all drivers implemented, and then, we hook Android into these drivers. Thus, broadly viewed, the XDAndroid project is divided into two parts: the kernel/drivers and the Android port.
When you look at the files in your Android directory, you'll probably see something like the following:
zImage: The Linux kernel and drivers.
modules-###: Additional drivers for the kernel. Your system will load without this, but things like wifi may not work, or you may encounter instability.
initrd.gz: Used in the Linux boot process.
system.ext2: Most of the Android framework.
rootfs.img: Additional parts of the Android framework that are customized for our devices.
data.img: This file contains what would be your internal memory on a real Android device. Whenever you install a program it goes in to here. A new empty one will be automatically created if you don't have one.
haret.exe: Reboots you from Windows into XDAndroid.
startup.txt: Commands passed to XDAndroid on bootup that are customized by the user.
ts-calibration: Contains calibration information for the touch screen. If you don't have this file, you will be prompted to calibrate your screen on startup.
AndroidApps: A folder where if you copy any apks into it, they will be automatically installed on bootup.

Good explanation manekineko!...I believe this is what op was looking for.
there is light at the end of the tunnel, it wont take much longer if the devs keep up this good work, until there can be made stable and good builds with good battery life etc. when the time is there i will create an complete noob friendly installation guide (with pics and maybe even an vid).
I'm currently trying to figure out which one to install!

tell me your phone type, so an rhod-100? 200? 300? etc.
and tell me what you prefer more, an good battery life and an stable running system without camera support OR less stable system, bad battery life but with camera support.
Tell me and i will help you

Seems I was wrong about that. It was the other way around, if the libs are disabled the phone won't sleep.
However, with FRX05 there's no need for the libs. FRX05 + GIT kernel or WisTilt2's newest kernel is all you need for cam.

Same for FRX04... It's in my bundle.

When I installed Kaosinate either v2 or v3 (I don't think v4), it didn't have a bootanimation in there.
Instead of any SAMSUNG or anything like that, I watched the raw boot process, text and all (like I've seen in maybe a Linux system before on bootup).
It looked a lot like a logcat dump while booting up.
I want that back, and I haven't found a ROM or a mod to do so, at all.
Someone seemed to think that init.rc would need to be modified to make it happen, but I want to find out how!
I've searched around and someone is still trying to find this in the Nexus One forums, and was satisfied with a custom bootanimation (which I am not)
http://forum.xda-developers.com/showthread.php?t=646279
I am wondering if I would be able to modify a flashable .zip with the init.rc from Kaosinate v3, and then throw it into jt's CM 6.2.0 ROM that I'm using, and find any success?
Has anyone else looked into, desired, or completed this process?
You need to rebuild the kernel to enable it. It requires some code changes as well as a few config changes. I also don't know if you can use boot animations after making the changes.
So it is a situation where I need to use a specific kernel then..
I think that this is what it looks like, when this guy gets Android on his iPhone, and you watch the boot process.
Good shot of it at like 1:52:
http://www.youtube.com/watch?v=5yO2KQHkt4A
Yeah, it is kernel specific, and by default, the stock Samsung source does not support what you want, so you'd have to make a few edits and also change some config options related to the changes as well.
This is not a thread to say ‘thanks’ to developers. Only post here if you have some input in this development progress, by either fixing bugs, or coming up with ideas (and ideally, try your idea and report what happens).
Having that said, let’s move on to where we are at the moment. Currently, we have a build which is based upon Ice Cold Sandwich 6.2 Test Edition for the HTC Desire HD. This build boots up by flashing my custom kernel on it, based on Flyer HC Original Kernel Source, with some patches:
-Quota2 Support
-Genlock Support
-Updated KGSL driver by applying Lord Clockans patches from his kernel
The ZIP we are working on now, can be downloaded here:http://w728685.open.ge.tt/1/files/9iI3CbF/0/blob?download
This ZIP contains a build which is mainly Lord Clockans ICS, with essential changes in the ROM to get it booting (we used LeeDroid’s Flyer HC as the donor ROM). This ROM is made for a HoneyComb HBOOT!
After you have flashed that ZIP, this is the kernel you need: http://ge.tt/9iI3CbF/v/1
You MUST flash this kernel to get it up and running, or it’ll just loop in the logcat complaining about unsupported stuff.
This set should do the following:
-Boot up (bootanimation resets after some time, it’s ok, it will boot within 5 minutes).
-Touchscreen works after you did this: open ADB Shell (by entering ‘adb shell’ on your pc,), and send the command “echo ‘1’> /sys/android_touch/event_google”. Now touchscreen should be working. (For some reason the file 90flyerhacks in /system/etc/init.d doesn’t do its job. If anyone has a clue > say so!) Also, the ntrig.c file in /drivers/input/touchscreen/ is modified in the kernel, don’t know if it helped though.
-Full Hardware Accceleration
-Screen is bugged at certain moments (seems to happen especially during things concering wallpapers. Rendering a wallpaper, showing a heavy LWP, etc.). The build.prop file contains some lines such as:
ro.fb.mode=1
debug.composition.type=gpu/mdp
debug.fb.rgb565=0
Perhaps we have to change these lines to get it running without issues (strange thing is, logcat doesn’t seem to make an issue about this). We can also try a recompile of the kernel using the entire driver folder from Lord Clockans kernel (it’s in /drivers/gpu/msm/ in his kernel, and /drivers/video/msm/gpu/kgsl_adreno205_hc in ours, moving the folder to where it should be causes issues, so we keep it like this for the time being).
-Sound is working
-Backcamera seems to be working fine, haven’t tested frontcamera.
-Hardware buttons under the screen aren’t working, and this should be a low
priority for now. It isn’t ideal to use them in ICS anyway (different button functions in comparison with the softbuttons), and I think we shouldn’t focus on this for now.
-GPS switch can be enabled, haven’t tested whether it works.
-Bluetooth switch can be enabled, but turns off automatically after about ten seconds.
-WiFi switch can’t be changed, logcat tells us that it can’t connect with /dev/rfkill, applying this patch in the ramdisk could fix it:
https://github.com/OpenSensation/an...mmit/da09360d70888a7e126871ab2ae5b218514cad18
-Power button and Volume buttons work fine.
-Pen works after we send the event_google command mentioned before.
If the ROM immediately reboots within 10 seconds and it seems like it’s looping, and you can’t even logcat, hold down Power and Volume Down until you get to HBOOT, select FASTBOOT, and enter ‘fastboot erase cache’ in the CMD/Terminal, and reboot, and it should work.
And that’s about it for the current things we know I think. If you manage to fix something, please write down and report what you did to fix it, so we can keep a list. I will work on a vendor folder using the known information, so we can compile a ROM from source, made for our device.
And last, but not least: don’t post here asking for release dates. We will do our utmost best to bring ICS experience to the Flyer, but do not bug us. Thanks.
Now let’s get this up and running guys! I will keep a log of what is fixed and what is not, so we can keep the thread organized. Else we’ll have 50 ZIPs around, not knowing which one is the right one et cetera.
Source code of kernel: http://github.com/Chaosz-X
Ramdisk will be uploaded tomorrow.
Donations are much appreciated, as I'm developing and building atm on a 1.67GHz Dual core...
Donations can me made to [email protected] using Paypal.
i suggest creating two repos... one for ROM and one for kernel... that way single file changes can be tracked even on ROM front, not just kernel...
willing devs can fork those repo and send pull requests to main repo when they get stuff working
I'm not a developer, and I have nothing but love for all the great devs that worked so hard to bring ICS to the Flyer.
Might I suggest, however, that instead of pursuing CM9 builds, the next effort be centered around porting the Android Open Kang Project (AOKP) ROM? In terms of features and customizations, it's considerably ahead of CM9, with numerous supported devices to boot.
I think this ROM, versus CM9, would give users the most flexible and dynamic ICS experience for their Flyer.

Does it work if you add
write /sys/android_touch/event_google 1
to the init.rc file?
Could you post the init.rc file where you trigger the init.d scripts?

yes that should work correctly
No, I didn't add that. I'll try it tomorrow (or one of you, if you have a Linux machine ready. Laptop with Ubuntu is having some issues atm, can fix it tomorrow).
So, assuming that's working, let's get to the display. We know that it causes issues, but how?
-Logcat doesn't error (except for HtcEbdLog, saying something about rotation, which seems to happen when glitches occur. Perhaps we need to swap the files?)
-At the very beginning, it does tell that initOverlay failed. This overlay-thing is baked in the ROM, and can be disabled in the ROM itself by setting an option to 'false' in the vendor setup. We don't know if it fixes the issue, but since the attempts to add this functionality to the kernel failed, it could be a better idea to fix it in the ROM to get rid of the error.
Any other suggestions?
Edit: and before I forget, tomorrow I'll check the ZIP for what is changed in comparison with the ROM it is based upon, so we know what we have to add in to a new build too.

Hello, all.
Attempting to help by working on the build.prop settings. I'm S-OFF with revolutionary and have my device fully configured with the Honeycomb HBOOT/radio/bootloader/etc.
After flashing the ROM and the kernel, the device would immediately reboot upon attempting to return to the main recovery menu. I had to fastboot oem rebootRUU and reflash Globatron's PG41IMG-WIFI-light-B10 zip to get recovery back.
The device never proceeded to the boot animation.

I can confirm this happened to me also. The only difference is that I was using the kernel for a port of mine, and it did the same thing.
Yes, it is known that for some reason, Go Back already reboots the device. It's no problem though, it works fine anyway. If it is really looping the bootanimation every ten seconds, keep Vol Down and Power pressed, until you get to HBOOT. Select FASTBOOT, and enter 'fastboot erase cache' in the terminal. Then reboot on the device, and it should boot up fine.
Also, kernel won't work on Honeycomb, haven't checked why it doesn't though (and I won't btw, our goal is not to make a new kernel for Honeycomb, but for ICS, where it does its job fine).
Kernel source is uploaded to my Github: http://github.com/Chaosz-X
Edit the CROSS_COMPILE for your toolchain, and it should compile fine (it does here).
Will add the link to the OP within 5 minutes, ramdisk will be uploaded tomorrow.
If chaos has a device tree set up for the Flyer/View, no build prop editing should be necessary, can just submit requests - but I don't notice it on the git.
Thanks for uploading, I'll have a look and see what has changed so far. It's a little difficult to keep track of the changes since there are no commits that document the patches applied over time, but I'll try to make do with what you've got.
Is this straight from flyer HC kernel source?

Hang tight for now. Wifi Does not work and the screen freaks out. I'm sure that these things will be fixed soon.
Going to upload ramdisk source within an hour, and try to apply a fix for WiFi, and try to fix the touchscreen by using the command in init.rc mentioned here earlier.
The new modem arrived, I have Internet again, so we have remote access to our Linux machine and can start compiling etc again
Indeed, we're grabbing AOKP source code now. Within about 2 hours we think, we'll start compiling the ROM for the HTC Flyer. Don't know if it will work out, but we have to start somewhere
Hi folks.
I'm an Android firmware developer (you can see my posts here in xda) that got a yoga book yesterday. For me it works at it should (by now) but my hacker soul speak to me and said: "at least take a look to see what you can get from this device". I don't have many time, so I can't spend time doing roms or fixing things by myself, but I can share with you some info I get and help you with my knowledge if someone is interested in "play" with this device.
First of all, I'm not responsable of anything that you can break following these steps. Almost all of them are tested and with some common sense you will not break anything, and if you break anything I will try to help you to fix it (if you are polite), but this is a work in progress and hacking and the possibility of brick the device is always there.
I only have the Android version without LTE, so I only tested in my Book.
So, here we go:
1) Secret codes:
I get this codes decompiling EngineeringCode.apk with apktool. Be carefull with them:
####0000# - Display version info
####7599# - Display hardware info
####8375# - Display baseband info
####1111# - Factory test
####2222# - Display SN
####7777# - Factory Reset???
####5993# - Display internal frameWork version
####7642# - Cut the power off to reload the PMIC - This command shutdowns the device. Just press the power button to reboot.
####5236# - Display LCD name
####2834# - ES close test
####8899# - open the ums mode default for debug
####3333# - offline log
####3334# - offline modem log
####9527# - Mediaplayer setting
####78646# - RunIn test
####6020# - switch country code
####59930# - Display current country code
####8746# - Enter engineering mode
####4227# - Enter engineer test
####357# - DLP_TEST
To use these codes, open the contacts app, press the search button and enter the code in the search bar.
2) OTA Images
You can get OTA images directly from lenovo servers. Just open your browser and paste this url:
http://fus.lenovomm.com/firmware/3....WW06_BP_ROW&action=querynewfirmware&locale=en
Change device model if needed (LenovoYB1-X90F or LenovoYB1-X90L)
Change curfirmwarever to a valid OLD firmware, this way you will get the next one in age.
Change locale if needed.
With this url you will get a download url at the end of the result page. In this case: http://tabdl.ota.lenovomm.com/dls/v...S000426_1705080316_WW06_BP_ROW_WC80C2A0F2.zip
These images are not full ota images, they are diff versions. This means that we can't use them to mod the image, or recover a bricked device, but this is a first step
3) Custom images
We don't have real sources to build a custom image (the lenovo's open source files are useless), but this doesn't mean that we couldn't modify stock images to take out useless apks or get better performance.
We can get this using an Android Kitchen and a full update image for the device.
As Android kitchen you can use SuperR kitchen (https://forum.xda-developers.com/ap...chen-superr-s-kitchen-v1-1-50-v2-1-6-t3597434)
As full image, I only tested the one here (https://easy-firmware.com/index.php?a=browse&b=category&id=19521) because I can't download any newer one.
I tested uncompressing it, deodexing the apks and doing a new image. But I don't test it in the device because I need to install twrp to flash the new image and I don't have time to test. But this should work, I did it many times so if someone is interested I can give steps to do it and support for testing.
If someone can get the latest full images, send then to me and maybe I can get some time to do some tests.
PD: Probably we could use this as a base to get LineageOS 14.1 working: https://github.com/latte-dev/android_device_xiaomi_latte/tree/cm-14.1
So, if you are interested in some hacking with the Yoga Book, contact me and we could team to get the most of this device.

Have you tried running it through Crossover? It may be in its infancy but i have got a few apps running OK with it.
I have the full "YB1-X90F_USR_S000196_1611040312_WW06_BP_ROW" I can upload somewhere if anyone can suggest a good site to do so without signing up? The file is about 2.5gb
It will be great if we could get the latest version, because maybe these older versions have older files that we have updated in our tablets.
Mixing files could give unknown problems
The current TWRP is based on the new Yoga Tab 3
I am starting to think they do not do full roms for this in the same way they do for a lot of their other devices.
We know the otas are available from tabdl.ota.lenovomm.com/dls/v6/ and are named according to the 2 builds that it bridges. As easy-firmware had the december full rom under the file name B1-X90F_USR_S000196_1611040312_WW06_BP_ROW-flashfiles.zip I had hoped that I could work out the file path to pull it down.
There were some interesting ideas here, https://forum.xda-developers.com/android/help/how-download-stock-roms-lenovos-ota-t3109507 but it seems there is a difference between phonedl.ota and tabdl.ota
Queries to full roms that work for phones, don't seem to work for the yoga book.
Anyone with more web knowledge able to pick this up? I am not sure the files are there but I feel they should be.
Good luck
Update: the downloads seem to be hosted via CloudFront. An Amazon service, but I can not find out a way of listing the available files. The latest full rom would be
http://tabdl.ota.lenovomm.com/dls/v6/YB1-X90F_USR_S000426_1705080316_WW06_BP_ROW_WC80C2A0F2.zip
But the Last 8 chars are random and we do not know what they are.
So we have two hopes. First work out the right query to the link from fus.lenovomm.com or two find a way of listing files available in tabdl.ota.lenovomm.com/dls/v6
Not sure I have got much further but ill keep trying when I can.
Hey, I should mention that I have some files that you may find helpful; I got them from the easy firmware website. They're all the .img files for each partition in Android (ie. boot.img, cache.img, config.img, factory.img, recovery.img, system.img) as well as: biosupdate.fv, bootloader, firmware.bin and gpt.bin. However, these of course aren't in the normal "flashable .zip ROM" format. So unless you know how to take apart these .img files they aren't very useful. If you need any more help or have any other questions about how far we've come on our own, feel free to ask. danjac also has great knowledge of our efforts.
Yes, I know how to use them, unpack, modify, etc. But what I want is the latest version, no a old version (I hav these files too). If you have them I can do some changes, debloat, etc.
Anyway, I see little interest in custom roms in this forum ( probably because it's not a device with a lot of users or the users are not the techy kind), so I prefer to help others with info than do a custom rom that only 2 or 3 people will use. Doing custom roms is a time hungry task and probably it doesnt worth the effort. Anyway this device is not full of bloatware like samsung ones, so it useable as it is.
As I said in my first post if anyone is interested I can give some hints and support to modify the full image (but only the latest one).
It's so sad that there are only a few interested owners of this tab - it's such a nice device but i fear the day lenovo decides to end their support for it. There will be no custom roms to switch to and keep the device alive - it will be a soon to be bit of old tech garbage BTW. I still use my Asus Transformer Prime because of the nice community
@NiffStipples I fully agree. This device is so powerful and its a suprise that it is invisible to the "market". In my humple opinion the normal ROMs aren't that bad besides missing updates but I would love to see all the power served through a custom rom. unfortunately programming is not my business

Have you tried running it through Crossover? It may be in its infancy but i have got a few apps running OK with it.

Interesting - is Crossover good (and does it require factory reset)?
Hi, It works well with some things and not others. Often the why and where are not obvious. It is basically "wine" the layer that allows some windows apps to run on a linux install. Tweeked to work with android. Just an install to put crossover on. Then another install (Within crossover), to put you app on crossover. If it doesn't work out of the box, there windows libraries you can switch out and dependencies you can install. (Eg: directx , .net) Even if your not technical. I would say get on the beta program and give it a try.
Hi! what do you mean by "lenovo's open source files are useless"? do you refer to this packet on lenovo's suppport site? download.lenovo.com/consumer/open_source_code/lenovo_yb1_x90f_l_osc_201608.zip
I've entered the Android YogaBook's BIOS and noticed that VT-X is enabled by default! With Limbo x86 we could get a fully working virtualized Windows or Linux, if it wasn't for... KVM. It seems like it's not enabled in Lenovo's default kernel. Could we get to recompile the kernel with this option on? i'm not a big android/ROM expert but i surfed the open_source_code folder from Lenovo and it seemed, to me, that we could rebuild the Kernel at least.
This could really change things!

How did you enter the bios? Can you boot from usb?
anyone managed to use swiftkey keyboard?
Hi everyone,
as title suggests, I'd like to "port" clean AOSP to be able to install and run it on the custom device.
Basically, the situation is following: I got a custom device, based on rockchip rk3288 SoC. The device currently runs Android 5.1 successfully. I'd like to update Android to version 6 (got AOSP sources and AWS builder image up and running), but the company that created Android v5 for us no longer exists.
Thus I am here to ask for advice(s) on how to proceed (or whether it even is a good idea to do that myself, given the fact that I have zero experience with Android ROMs development), possibly a step-by-step guide on what to do.
The question is, do I just find drivers for hardware components present in the device (usb hub, ethernet, etc.) and just somehow "link" those to existing sources (of AOSP) and just run the build with different parameters? Or do I need to build a whole new kernel for the given device-OS combination?
Thank you for any advice or opinion!
Well this is an interesting one. There are several routes you can take here.
If you have the kernel source code, and the source code for the drivers, you could probably build the kernel from source and use it to boot Android, however, as that's unlikely, you're looking at a more regular porting process, which usually consists of pulling the vendor blobs from the existing Android system, building AOSP/Lineage with those blobs involved, and hacking together a new ramdisk that HOPEFULLY will be compatible. It's a very long and very tedious process, but it's certainly possible.
From that you'll then get in to the debugging stage of finding out what works out of the box, you'll very well need to make changes to AOSP for it to work on that SoC.

Thanks for pointing in the right (or at least some) direction! I found some guide on porting ROMs which I followed, basically like you said. So I just replaced some files in System image. Will flash later today, so maybe I will get some results!

So I was following this tutorial, although found some irregularities, let's say: For example, none of those 2 folders contained init.d/ directory, thus I didn't update it. Also, I haven't found META-INF folder therefore haven't updated updater-script.
Basically, when I did (or at least what I think I was doing was that I took /system partition from our current ROM, that is working on that custom device and replaced stuff in there by stuff from the new system I wanted to port. My idea from what I've read was that i took kernel (and boot/recovery) from the original, working ROM and "injected" the new system onto it. Is that correct? Is that what I needed to do? Because the problem is, I cannot boot into the system (might as well be because of Kernel version, because I am trying to port Android 6 on Kernel 3.10. which was used in the current ROM running Android 5). It looks like the device is stuck in bootloader, or "somehow doesn't know what to start" (sorry, I can't put it better), displaying only my device's logo.
When I connect it to the computer via USB cable, running adb devices shows me that device, but when I try to access shell using adb shell I got error saying that /system/bin/sh wasn't found, which made me thinking that somehow the /system partition isn't "linked" properly, like I stated in the beginning.
Was I doing everything correctly? Do I need to do something above that? (maybe do you know about some tutorial). I am trying to port AOSP 6 Android.
Thank you!
